LANGUOR. A name given in vegetable 

 Pathology to that condition of plants in 

 which, from unwholesome food, bad drain- 

 age, frequent want of water, &c, they fall 

 into a state of premature decrepitude. 

 This is well known in French vineyards 

 under the name of Goupissure, and is fa- 

 miliar to all fruit-growers when the subsoil 

 is ungenial. TVhen once this condition is 

 set up, it is difficult of remedy, if not past 

 cure altogether. The removal of the cause 

 is the only rational treatment, and this is 

 not always possible. [M. J. B.] 



LANKESTERIA. A genus of Acanthacece, 

 containing two species, natives of Central 

 Africa. They are hairy shrubs with ovate 

 entire leaves, and yellow flowers in short 

 axillary spikes, having a calyx of equal 

 linear sepals, subtended by two bracts ; a 

 long slender corolla-tube, and one-sided 

 five-parted limb, two exserted stamens, 

 and a simple capitate stigma. The genus 

 is named after Dr. Lankester, a well-known 

 English botanist. [W. C] 



LANSA, LANGSAT, or LANSEH. The 

 fruit of Lansium domesticum. 



LANSBERGIA. A South American genus 

 of Ttidacece, related to Phalncallis and Cy- 

 j pella, from the first of which it differs in 

 ' having the sepals all closed and converging, 

 in the cells of the anther being adherent 

 ! to the lobes of the style by their whole 

 length, and in the stigmas being minutely 

 I crested and not petaloid ; while the second 

 j is known from it by its stigmas being lobed, 

 I acute, and fringed at the upper side with 

 j acute homy crests. The outer divisions of 

 I the perianth are large and concave, the 

 | inner narrow and involute. L. caracasana 

 ; has tuberous roots, simple stems, equitant 

 , leaves, and yellow fugacious flowers, spot- 

 | ted with brown or black. [T. M.] 



j LANSIUM. A genus of Meliacece, con- 



' fined to the East Indies, and consisting of 



1 trees with imparipinnate leaves, and axil- 



! lary flowers arranged in panicles. The 



'■ calyx is composed of five sepals ; the co- 



' rolla of five petals ; the ten stamens are 



; formed into a tube. The; fruit is a corticate 



j berry, having five cells, each ceircontain- 



ing one or two seeds. This berry has a cool- 

 ing pleasant, taste, and hence they are some- 

 times cultivated, and sold in the Canton 

 markets. L. domesticum (known as Lansa, 

 Langsat, Lanseh, Ayer-Ayer, or Bejetlan, 

 in the different languages of the East In- 

 dies; has a fruit as large as a pigeon's egg, 

 of a yellowish colour without, and whitish 

 within, which is highly esteemed, and eaten 

 either fresh or variously prepared. The 

 wood is used by the Malays. [B. S.] 



LANTANA. A considerable genus of 

 Verbenacece, containing upwards of fifty spe- 

 cies, chiefly from tropical or sub-tropical 

 America. They are shrubs, or rarely herbs, 

 with flowers in pedunculate axillary heads, 

 rarely lengthening into spikes. The calyx is 

 small, truncate or sinuately four-toothed ; 

 the corolla tube slender, with a spreading 

 four or five-lobed limb ; there are four in- 

 cluded stamens; the ovary is two-celled; 

 and the fruit is a drupe, the kernel two- 

 celled, or divided into two nuts. [W. C.J 



LAPAGERIA. A genus of PMlesiacece, 

 consisting of twining undershrubs, with 

 alternate cuspidate somewhat reticulate 

 leaves, and solitary one-flowered peduncles, 

 the perianth coloured, six leaved, and some- 

 what bell-shaped ; and the stamens six, in- 



Lapag 



serted at its base. The fruit is a one-celled 

 berry, with numerous seeds. They are na- 

 tives of Chili. L. rosea, with its white 

 variety, are two of the most beautiful plants 

 grown in modern greenhouses. [J. H. B.] 



LAPEYROUSIA. A genus of Iridacece, 

 consisting of half a dozen species from the 

 Cape colony, allied to Anomatheca, in the 

 long slender tube of their perianth, and 

 spreading lobes, but these are much more 

 equal, the stigmas are more deeply cleft, 

 and the capsule is distinctly three-lobed- 

 They have tuberous bulbs, simple stems, 

 with sheathing leaves, and terminal elon- 

 gated flower-spikes, each flower in the axil 

 of a leafy bract. Three species, L. flssifolia, 

 L. anceps, and L. corymbosa, were formerly 

 cultivated among our Cape Iridece, but are
